The Influence of Rice Husk on the Physical Properties of Portland Pozzoland Cement at the Cement Industry Scale

Abstract

This study aims to determine the effect of rice husk as a source of substitute fuel on the manufacture of cement at the industry scale. The parameters tested include the physical properties of the cement consisting of the Blain fineness test, false set, cement setting time, and mortar compressive strength at 3, 7, and 28 days. The average values for the results of these tests on cement produced using rice husks as a substitute fuel were 380 m 2 /kg, 81%, 132 minutes, 253 minutes, and 225, 298, and 379 kg/cm 2 , respectively. Based on the test results, we have shown that rice husk ash has a good effect on the characteristics of cement type I which still meet the standards of SNI-2049-2015.
